Existence Of Solutions For A Class Of Singular Semilinear Evolution Equations As A Whole Reconciliation Blow

From the ninties to today, the studys of semilinear development equations with singular cofficient^[1-5]were done very well. The studys of nonlinear development equation system^[7-22] were done very well, too. But, the studys of semilinear development equation with singular coefficient are very little. We discuss one kind of semilinear development equations with singular coefficient.We shall assume henceforth that u.(x) and v.(x)are nonnegative, continuous and bounded functions. A are N dimension laplace operator.In the second section, We discuss one kind of semilinear development equation system, get the existence of nonnegative global nexistence of nonnegative solution for the problem.In the third section, We discuss the blow-up problem.
